FLOOR-PLANING MACHINE.

SPECIFICATION forming part of Letters Patent No. 414,275, dated November 5, 1889.

Application filed October 26, 1888. Seal No. 289,191. (No model.)

To all 'whom it may concern:

Be it known thatwe, HONESTUS M. ALBEE and CHARLES R. HEDDEN, citizens of the United States, residing, respectively, at Newark and East Ora-nge, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Floor- Planing Machines; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of this invention is to facilitate the operation of smoothing wooden iiooring, both by the operation of planing and sandpapering, and to reduce the amount of manual labor involved in such operations, and consequently the expense involved in the same.

The invention consists in the improved licor-planing machine, and in the arrangements and combinations of parts, substantially as will be hereinafter set forth, and finally embodied in the clauses of the claim.

Referring to the accompanying drawings, embraced in eight sheets, in which like letters of reference indicate corresponding parts in each of the several figures, Figure lis a side elevation of our improved device. Fig. liL is a section thereof on line Z Z. Fig. 2 is a plan of the same. Fig. 3 is a plan of a reel employed when electricity is the motive force. Fig. 4 is a section of the same, taken on line Xof Fig. 3. Fig. 5 is a section of the bed of the carriage, taken on line yy of Eig. l. Fig. 6 is a sectional view taken on line Z, Fig. 2, illustrating the construction of the carriagewheels or anti-friction bearings. Fig. 7 is a face view of a piece employed in connection with said bearings. Eig. S is a plan of the bearings for the planing-irons or cutters, the cuttercarrying shaft being in section on line Z Z of Fig. 9. Fig. 9 is a side elevation of said bearings, certain parts being shown in section. Figs. 'lO and ll are views showing the rear of the carriage and a supplemental wheel adapted to raise the carriage and rear wheels from the iioor, so that the said carriage may be turned thereon without scraping the ioor by sliding the wheels laterally, and Fig. l0 being a section taken on line Y Y of Fig. 11. Fig. l2 isa det-ail plan, and Fig. '13 a sectional view taken on line lV, of a sandpapering-wheel which may be employed in connection with the carriage-shaft after the planing operation is finished; and Fig. 14 is a detail side elevation showing` the preferred construction of a certain lever shown in connection with the guide-handle.

In said drawings, a indicates a low carriage-body, made of wood or iron, or both combined. Said carriage-body is supported by wheels l) b, by means of which the carriage may be readily moved from one part of the flooring to another. Said wheels are adjustable in their relation to the body, as indicated in Fig. 6, whereby the body can be raised or lowered at either of its corners to wheels is shown, c c being the wheel axles or shafts; d, the boxes for the said axles, which are pivoted on the bed of the frame or upon a casting d", fixed to said frame, as at e, the box being provided with an arm f, which extends to the pivot.

g is an adj usting-screw by means of which the box and the wheel are adjusted in their relation to the carriagebody, the said body being raised or lowered thereby, and hi is a tiepiece adapted to hold the parts iirrnly together after the adjustment is effected, the said tie being' secured to both the carriage-body or the said casting d and box by set-screws or like fasteners i 'L'. Said tie-piece is slotted, as at j, to allow the same to slide on one of said screws in effecting the adjustment. The ad j Listing-screw is provided with a lock-nut 7e'.

Upon the carriage, or forming part of the same, is arranged a heavy tubular or hollow casting Z, which provides bearings m m for pulley-shafts fn. Said casting may be bolted to the body a, as indicated in Fig. 5, or may be fixed thereon in any suitable manner. By being tubular, as shown, it provides a partly-= IOO closed passage for the belting and gives rigidity to the movable arm o, pivoted on the pulley-shaft. On the end of the movable arm o is arranged another vertically-adjustable arm p, which carries the cutter-shaft q. Said arm p is adjusted in its relation to the arm o by a hand-'screw 10, which enables the cutters to be raised or lowered in their relation to the iioor, so as to regulate the depth of cut at will.

Upon the carriage elevated table r thereon, is arranged a motor s. This latter is preferably an electric motor of any'ordinary and suitable construction, although we may employ steam, compressed air, or any other motive force. The said motor actuates the driving-shaft t and pulley a,

and the power is transmitted to the cuttershaft q by means of the belts and pulleys c w fv w 'u2 'L02 fc3 w3, the speed of the .cutters being greatly facilitated by the reduction in the size of the pulleysas they approach the cutter-shaft.

The cutter-shaft and the said parts depending thereon are shown more clearly in Figs. 8 and 9. At the lower end of said shaft is ar ranged a transverse tool-holder 2, which is set on said shaft q by screw 3 or by any other suitable means, so that the said tool-holder will revolve in a horizontal plane with said shaft. At the ends of said holderare arranged 1he planing-irons or cutters 4 4C, which extend downward to engage the floor. Saidcut-4 ters are adjustably arranged inthe holder, and may be of any construct-ion adapted for the particular line of work for which they are intended.

' Extending downward from theouter arm p is a 4segmental frame 5, which is grooved or recessed, as indicated in Fig. 9, to receive a steadyingarm 6,formed on a collar 7, carried by the tool-shaft q. To secure greater firmness, the steadyingarm may have, and preferably does have, -a wheel 8 adjustable thereon,which engages the floor. By this construction the tool is given a very steady movement, and as -a result the tool is effective in giving a very smooth finish to the iioor. The collar -7 also carries a foot guard or shield 9, adapted to prevent the feet of the operator from coming in contact with the cutters.

To raise the cutters or planing-irons from the floor for the purpose of inspection, we have provided a lever 12, suitably fulcrumed on the arm p and engaging a grooved collar 11, fixed to the shaft, so thatv by depressing the lever the shaft will be raised and the cutters lifted from contact with the iioor. Under certain conditions the said lever may be a small one projecting `laterally from the arm p, as indicated in Fig. 1, but ordinarily, for purposes of convenience, we prefer the construction shown in Fig. 14, where the said lever extends vertically and parallel with or nearly parallel with the guiding-handle 12, sb that the two may be readily grasped together, and by pressing the lever toward the a, preferably upon an handle 12 the cutter will be raised. By this construction the necessity for stooping will be obviated. s

The handle 12 isrigridly fixed to the arm p and extends .upward therefrom, enabling V8o from one partV of the room to another more distantfrom the battery, we have arranged on the carriage a reel 13, adapted to take up the fullness in the conducting-wire when the carriage is close to the battery and pay it out as the carriage travels therefrom, so that there will be no danger of the wire getting in the way and interfering with the planing opera-Y tions. Said reel consists of a turn-table 14, suitably held upon the carriage, preferably in an elevated position, such as is provided by the post 15, so that thewires will not Jin-v terfere with the other Workingv parts. The 'wires to the motor are connectedwith the metallic bearings 16, while the wires to the battery pass through the reel-drum 17 and are connected to the reel-spindle 1S. A suitable crank 19 may be employed to turn the y Ioo cially provided at the rear of the carriage to receive said lever. By depressing the leverhandle 24 the carriage is raised andY may easily be turned by pushing or pulling on the lever-handle in the desired direction.

After the iioor is properly planed by the cutters or planing-irons we substitute for the holder 2 a sandpaper-holder 25. (Shown in Figs. 12 and 13.) This may be of any ordi- IIO nary construction adapted to allow of a sheet of sandpaper being secured therein, so that it will present a broad surface to the floor.

In operating the device the motion of the motor is transmitted to the cutter-shaft 'q by means of the Abelts and pulleys shown and described, causing the same to rapidly revolve, and thus cause the plane-irons secured on the holder 2 to rotate, the path of one iron being a little in advance of the other, either in depth or in its nearness to or distance from the axial center, as will be understood. By moving the handle 12 the machine and cutters may be brought to the desired position on the floor.

We are aware that heretofore a frame provided with Vpivotal arms and a rotary cutter arranged together have been employed in nishing'boards, the said parts, however, not being so arranged as to finish the boards when the latter are down in the flooring vover which the carriage is being wheeled. In our improvements the cutters extend down to the plane of the wheel-bearings, or, in other words, to the floor or surface over which the wheels or other supports for the portable carriage are moved, as will be understood. Thus the boards are planed or finished collectively after they are fastened down in their final positions on the beams or sleepers, and not individua-lly by carrying the boards to the machine and passing them under the planing-iron, as will be understood.

Having thus described the invention, what we claim as new isl. The improved floor-planing machine combining therein a movable carriage having a pivotal arm provided with a rotating cutter extending down into engagement with the floor, over which said carriage is movable, substantially as and for the purposes set forth.

4. The improved floorplaning machine combining a carriage-body having adjustable wheels adapted to admit of the said carriagebody being raised or lowered in its relation to the floor, a pivoted arm, and a revolving shaft carried thereby, and planing-irons, all arranged and combined substantially as and for the purposes set forth.

5. The improved floor planing machine combining a carriage-body movable on the floor to be planed, an electric motor supported by said body, an arm vibrating in a horizontal plane and carrying a cutter-shaft, belts and pulleys transmitting power from said motor to said shaft, and a conducting-wire for conducting the electric current to the motor, and planing-irons or cutters extending into engagement with the floor, all said parts being arranged and combined substantially as and for the purposes set forth.

6. The improved floor planing machine combining therein a carriage-body having adjustable boxes d, wheels journaled in said boxes, and adj ustin g-screws whereby the said body may be adj usted to inequalities in the iioor, and suitable planing-tools and means for operating the same, substantially as and for the purposes set forth.

7. The improved floor-planing machine combining with the body and wheels thereof and planing mechanism the boxes d, having arms f, pivoted at e, adjusting-screws g, and tie-pieces h, all arranged and adapted to operate substantially as and for the purposes set forth.

S. In combination with the carriage-body having a pivoted arm carrying a rotary cutter, a steadying-wheel secured to said pivoted arm and engaging the floor, substantially as and for the purposes set forth.

9. The improved iioor planing machine combining with the movable planing-carriage a lever fulcrumed on a supplemental wheel and adapted 'to raise one end of said carriage and turn the same, substantially as and for the purposes set forth.

l0. In combination, a wheeled carriage adapted to be moved over the floor to be planed, a motor supported on said carriage, cutters or planing-irons extending into engagement with said floor and arranged on cuttencarriers operating under the influence of said motor, and a handle for moving the carriage from place to place on said iioor by hand-power while said cutters are in operation, substantially as and for the purposes set forth.
